Answer: Y = 7x

3x7 = 21

5x7 = 35

8x7 = 56

10x7 = 70

3x7 = 21

5x7 = 35

8x7 = 56

10x7 = 70

The equation y+ 3 = 5(x - 3) represents a linear function. What is the y intercept of the equation

Answer:

The y intercept is when x=0

When x=0,

y+3= 5(-3)

y+3= -15

y=-18

the y intercept is thus -18.

WHOEVER SOLVES IS A GENIUS! Chris visited the local Pizza Shack to purchase one pizza for each member of his Scout Troop. On arrival, he realised that he had mislaid the list he had made of the pizzas that had been requested. He knew that there were 32 people altogether and that all 3 vegetarians in the Troop wanted mushrooms only. He also remembered that the same number of people wanted just the chicken topping as wanted a plain pizza. Alex, a Young Leader, was able to help by recalling that: 12 people requested toppings that included chicken, 10 requested toppings that included pepperoni, 9 requested toppings that included mushroom, 1 person wanted all 3 toppings, 2 wanted chicken and pepperoni only, 2 wanted peperoni and mushroom only. What was the final order that Chris placed at Pizza Shack?

I HAVE NO IDEA WHAT THE ANSWER IS!!! CAN YOU TELL ME???

He want's 39 pizzas!!

Find the length of each side of the triangle determined by the three points P1,P2, and P3. State whether the triangle is an isosceles triangle, a right triangle, neither of these, or both. (An isosceles triangle is one in which at least two of the sides are of equal length.) P1=(−1,4);P2=(6,2);P3=(4,−5)

Answer:

The triangle is both an Isosceles triangle and a right triangle.

Step-by-step explanation:

Given the vertices of a triangle.

and

We find the distance between all the points to determine the length of each side of the triangle.

Distance between any two points, say, and is:

Length between and , (Side 1) :

and

Distance =

Length of Side 1 = units.

Distance between and , (Side 2):

Distance =

Length of Side 2 = units.

Distance between and , Side 3 :

Distance =

Length of Side 3 = units.

Note that the length of Side 1 = Length of Side 3.

That means the triangle is Isosceles.

Also, For a triangle to be right angle triangle, using Pythagoras theorem we have:

(Side 1)² + (Side 3)² = (Side 2)²

i.e, 53 + 53 = 106

Hence, the triangle is a right - angled triangle as well.

If 5c-2b=15 and 3b-4c=12, what is the value of b+c? (a) -27

(b) -3

(c) 8

(d) 27

(e) cannot be determined with the information given

D).

using linear combinations you can add the 2 rows and it will get you b+c=27.

-2b+5c=15

3b-4c=12

b+c=27

using linear combinations you can add the 2 rows and it will get you b+c=27.

-2b+5c=15

3b-4c=12

b+c=27

Everyday there are 4 times more like on an internet video of a horse which is modeled by the function c(n)=(4)^n-1 where n is the number of day since the video posted on the first day there were 100 likes what is the function that shows the number of likes each day

Answer:

Step-by-step explanation:

A better way to write the first function would be:

c(n) = 4*c(n-1), meaning that the number of likes is equal to four times the number of likes from the previous day.

On the first day, c(n)=c(0) = 100

Therefore:

C(n) = 100 * 4^n

Let's plug in a view values to test our function:

When n= 0 (first day)

C(0) = 100 * 4 ^0 = 100*1 = 100 likes

C(1) = 100 * 4^1 = 100 * 4 = 400 likes, four times the previous day

C(2) = 100 * 4^2 = 100 * 16 = 1600 likes, four times the previous day

And so on. Our function is an accurate descriptor of the model.

Solve 64÷4 using an area model

The ANWSER is 16 I don't think I can show you a area model try your best you can make 64 squares the get and put them into groups of 4 if that helps and there should be 16 groups

7. A line in the Cartesian plane passes through the points (1, 3) and (5, 4). What is the slope of the line? A. 1/4 B. –4/1 C. 4/1 D. –1/4

A

to calculate the slope m , use the ' gradient formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (1, 3) and (x₂, y₂ ) = (5, 4)

m = = → A
